A driver amplifier circuit is provided which includes a voltage level shifting circuit and an Op-Amp. A positive power supply terminal and a negative power supply terminal of the Op-Amp receive a first reference voltage and a second reference voltage outputted from the voltage level shifting circuit, causing a DC voltage level of an output signal to be equal to 0V. Meanwhile, the absolute value of a voltage difference between the first reference voltage and the second reference voltage is equal to V<SUB>DD</SUB>, meaning that elements in the circuit operate without risking a high-voltage damage.
